How is the case on the non-woven bag printed?

1, screen printing: This is a common printing method, and the price is moderate, so many manufacturers adopt some methods. In this printing method, the film is made of logo documents, and then the screen can be dried through the film. After the LOGO is dried, the screen can be made into a printing plate before printing. Printing is very important. If printing is not good, the printing effect will be poor. There are two kinds of screen printing: manual screen printing and machine screen printing, which is an ancient printing method.

2. Offset printing: the abbreviation of machine offset printing. By making a soft offset printing plate and sticking it on the printing roller of the printing machine, one or more bags can have their logo on each round. This printing method is mainly fast and effective, which is worse than screen printing, but because of its low price, more and more manufacturers adopt this printing method.

3. Peritoneum: The finished product processed by this method is usually called laminated non-woven bag. Firstly, the traditional gravure printing process is used to print the pictures and texts on the film, and then the film printed with patterns is compounded on the non-woven fabric by the laminating process. Generally, this process will be adopted for patterned non-woven bags with higher requirements or more colors. It is characterized by exquisite printing, machine production and fast production speed. The finished product has excellent waterproof performance and durability better than that of non-woven bags produced by other processes. Peritoneum: There are two kinds of bright membrane and matt membrane, but the cost is higher.

4, thermal transfer: belongs to the special printing in printing! This printing method needs to be completed by an intermediate medium, that is, the graphics and texts are printed on the thermal transfer film or paper first, and then the patterns are transferred to the non-woven fabric by the thermal transfer equipment. The commonly used medium in textile printing is thermal transfer film. This is beautifully printed and rich in layers, comparable to photos, but the printing cost is higher.

5. Copperplate printing: The source of copperplate printing has data showing that it first appeared in the Song Dynasty and was used to print paper. This technology was also applied to the back non-woven bag. The process of making copper plates is complicated and slow. At present, it takes 6- 10 days to make a copper plate, and its plate cost is relatively high. But it has long service life, good printing effect and high speed, so it is widely used.

6. Thermal sublimation: it is a technology to transfer the graphics printed on the surfaces of different materials through the action of water. Water transfer printing can be divided into water mark transfer printing and water coating transfer printing. You can print the drawings you want on various objects only by water, which is the most widely used printing at present. As long as the special adhesive film is placed on the water surface and sprayed with reagents, objects of various shapes can be coated with a new coating, and the effect and durability are almost as ubiquitous as baking paint. However, the cost of this process is relatively high. This is the printing technology of Wanglai nonwoven bag.
